It has to do with the job signs in Total Economy. I believe they cause issues when the server is restarted. Regardless, this is an error that is caused by Total Economy that has been fixed for the latest release.

Total Economy v1.4.1 has just been uploaded. This update includes a bug fix for job signs as well as the ability to view the balance of offline players using the view balance command. If you encounter any issues please post them here: Issues.

Hi, we’re making a Pixelmon server, and we use your plugin, but we thought about a command that you didn’t add in yours : The ability of taking money from a player, like /balance take [player ] [amount]. Could you fix this please ?

I am making progress on the latest version of Total Economy. Currently only small additions but I am hoping to add, or at least start, some bigger additions. You can follow the progress over on GitHub.
